From what I've seen only covers that specifically were made in the patch work for those weapons. This happened earlier with Cannons in Legend and Shining Rods in Tempest and I've seen it happen with Desperados in EMS too. As far as I know, only the weapon of the xenon set (which has +5 att/matt and works with all weapons) works with Energy Swords/Beam Whips. If there are any more, I haven't been able to find them in the EMS CS.
